Embodiment Construction

[0029] figure 1A sectional view of a partition device 10 embodied as a partition wall is shown. The separation device 10 is arranged to separate a space 12 (shown above) threatened by fire from a space 14 (shown below) to be protected against fire. Electrical equipment, not shown, which is powered by means of a cable unit 16 is arranged in the space 12 . The space 12 can correspond, for example, to the interior of an electrical box or an engine compartment, in which a fire could potentially be triggered due to a failure of an electrical device. The partition device 10 preferably corresponds to a housing wall of a housing surrounding the space 12 .

[0030] In the exemplary embodiment under consideration, the cable unit 16 corresponding to the cable bundle runs from the space 12 outwards through the cable connection 18 of the partition device 10 into the space 14 . The cable connection 18 has an opening 20 , which is freed in the partition device 10 , through which the cable...

Abstract

The invention relates to a fire protection device for a cable bushing (22) leading a cable unit (16) from a fire-risk area (12) to an area (14) to be protected against fire, comprising a fire protection means (32) that is provided for protection against the spread of a fire into the space (14) to be protected through the cable bushing (22). In order to provide a fire protection device that offers high flexibility in the use of cable bushings and allows subsequent repositioning of the cable, the invention proposes that the fire protection means (32) is designed as an assembly component.

Description

technical field [0001] The invention relates to a fire protection device for a cable lead-through, which guides a cable unit from a space threatened by a fire into a space to be protected against a fire, the fire protection device having a fire protection device which is provided for protection against the spread of fire through the cable lead-through into the space to be protected, wherein the fire protection device has a structural unit and a base body made of an intumescent material, The structural unit is fixed on the base. Background technique [0002] In the event of a fire spreading from a threatened space equipped with electronic equipment, the cable entry which forms the interface between the threatened space and the space to be protected represents a safety-critical weak point without special measures. The spread of fire through this unprotected point cannot be avoided because it does not meet the requirements for complete sealing without protective measures. [...
